There is a FM modulator thing that can be fiited into the arial in of the
stereo. This would do what you want but wont play music (from the stereo) at
the same time, unless its to play mp3's from the 910 of course.

Cheers, I'll check it out.

Is there any way of doing this without using FM, though?
